caption_attribution_description: English: Magruder Plots, Oklahoma State University–Stillwater. Boundaries identified by pink posts; unfertilized "check" plot visible with less stubble. This is an image of a place or building that is listed on the National Register of Historic Places in the United States of America. Its reference number is 79002018
context_page_description: The Magruder Plots are experimental winter wheat field plots at Oklahoma State University established in 1892. They are the third longest running such field trial in the United States, following the Morrow Plots established in 1876 at the University of Illinois at Urbana–Champaign, and the Sanborn Field established in 1888 at the University of Missouri. They are examples of long-term experiments.
  Originally planted in the fall of 1892 by A. C. Magruder, first
  professor of agriculture at Oklahoma A & M,
  these plots were established to obtain information on the
  ability of the soil to continue to produce good yields of wheat without
  fertilization.
  Researchers have conducted hundreds of experiments
  comparing various fertilizer treatments with manure applications and
  without such treatments. The plots became the center for wheat soil
  research in the region and provided constant data which helped farmers
  get maximum yield from their arid climates and naturally dry soils.
